The coroplast stab with the elevator cut out and pre-cut, easy start for this model.
|
|
The fin and stab glued together. This almost completes the tail section constuction of the plane.
There really is nothing to it. I used some 6 minute epoxy to glue the two pieces of coroplast together.
|
|
I used a 4oz. Du-Bro tank to supply the fuel to the engine. I used a dremel tool to trim the brass fuel tubing
to the proper length.
|
|
The cutting of the firewall ply was a bit tricky, I didn't have a tool that would cut 1/4 inch plywood so I had to
step out to the local hardware store to pickup a jigsaw. Once I got the jigsaw it only took few minutes to cut the
firewall to shape. I used a dremel tool to sand the edges for more precise shape.
|
|
I've obtained an O.S. Max .25 LA engine to power the Zero. This model was designed for a .20 engine, so a .25 LA engine
should suffice for sure. Mounting the engine onto the glass packed engine mount was a snap.

I've used 3M 77 spray glue to glue the two halves of the canopy together. Took several minutes before the two
halves were joined permantenly. However I noticed a small gap between the two halves, I hope it won't be a problem
in the final construction.
|
|
I've used more 3M 77 glue to attach the firewall to the foam fuselage of the plane. I was really surprised how
effective this glue is. It seems to just slightly melt the foam so it adheres better.
|
|
After a very messy sanding session, the fuselage is starting to look like a shape of a Zero wing. The shape of the
fuselage has been sanded down to meet the shape of the firewall.
|
|
I've used a dremel tool to bore out the space for the fuel tank. It only took me few minutes to get the cavity
deep enough to accept the fuel tank. I've also drilled two holes in the firewall to accept the fuel intake and
pressure hoses.
|
|
I've glued the fuse doublers using the spray on glue. I've used a rubber band to hold the edges tighter
around the fuseleage. Even after scoring the coroplast with a blunt object, it still didn't really want to
conform to the shape of the plane.
|
|
The wing has been finished and glued to the body with goop. Engine installed and the throttle and elevator wires set.
The plane is almost ready to fly.
|
|
The doublers needed to be cut out to fit the engine muffler and the adjustment needle.
|
|
The elevator control horn was a pain to install, the coroplast is pretty flimsy so securly installing the horn
was a challenge. Setting up the angle of the horn relative to the servo was a pain too.
|
|
The muffler is too tight against the body. I've ordered a muffler extension to add some clearance.
|
|
The packing tape is horribly wrinkled around the edges of the wing. I gotta figure something out to make it more presentable.
|
|
The wing servo is sticking out a little from the bottom. I'll need to build a small servo box to protect the servo during landings.
|
|
The servos were installed using normal silicone. I've taped the servos with electrical tape so that they can be easily
taken out when needed.
|
|
I had to cut out a small groove to clear the elevator wire from rubbing against the body.
